Library Blog
USB Device Library presents the user set of functions required to handle USB device peripheral. A embedded user application program uses API defined in this library to access USB device peripheral. The library has set of functions implemented within library and also uses set of callback functions which will be implemented by application designer outside of the library. Library internaly handles standard device requests, leaving the user to process other requests.
As example of use of this library, following USB device classes are implemented:
HID (Human Interface Devices) class with mouse functionality
MSC BOT (Mass Storage - Bulk Only Transport) class.
CDC (Communications Device Class) class.
USB Device Library features following functions:
USBDev_Init
USBDev_IntHandler
USBDev_GetDeviceState
USBDev_StallEndpoint
USBDev_CtrlStall
USBDev_ClearStallEndpoint
USBDev_RegisterGetDescriptorHandler
USBDev_RegisterEventHandler
USBDev_RegisterSetupReqHandler
USBDev_RegisterDataReceivedHandler
USBDev_RegisterDataSentHandler
USBDev_ConvertStringToDescriptor
USBDev_SendPacket
USBDev_SetReceiveBuffer
USBDev_CtrlDataAck
USBDev_CtrlSendData

Rotary W 2 Click is a compact add-on board that allows you to add a precision input knob to your design. This board features the TLC5925, a low-power 16-channel constant-current LED sink driver from Texas Instruments that, combined with a high-quality rotary encoder from ALPS, the EC12D1564402, allows you to add a precision input knob to your design. It also features an LED ring composed of 16 individual white LEDs that can be used to represent the encoder position more visually.

SPI Isolator 3 Click is a compact add-on board that contains a digital isolator optimized for a serial peripheral interface. This board features the MAX14483, a 6-channel 3.75kVRMS digital galvanic isolator with a very low propagation delay on the SDI, SDO, and SCLK channels from Maxim Integrated. Besides a second enable control input, which allows MAX14483 to isolate multiple SPI devices, and an auxiliary channel available for passing timing or control signals from the master side to the slave side, the MAX14483 also possesses power monitors provided for both power domains to signal if the opposite side of the isolator is ready for operation.
